Abstract

PURPOSE: To provide a method for bonding a pair of thermoset composite structures by using a thermoplastic adhesive layer. CONSTITUTION: Thermoset composite structures 19 are bonded together using thermoplastic adhesive strips 10 which are comprised of a layer of suitable thermoplastic material 12, a layer of dry fiber reinforcement 16 which is partially embedded in the layer of thermoplastic material. The surfaces of uncured thermoset composite structures 19 are prepared by positioning adhesive strips 10 with the thermoset resin side towards the composite structures. The composite structures are then cured by conventional means. Subsequent to curing, the bonding surfaces coated with the thermoplastic adhesive strip 10 are pressed together and heated to fuse the joint. During this process sufficient heat is applied locally to melt and fuse the thermoplastic adhesive material without degrading the adjacent composite structure. The joint is allowed to cool using the composite structure as a heat sink.

ている。BACKGROUND OF THE INVENTION Thermosetting composite materials are widely used as structural materials in the aircraft industry. This type of composite material provides a relatively high strength and lightweight structure. To obtain high-strength bonds in thermosetting materials, expensive methods in combination with mechanical fixing devices are currently employed.

等に再度交換することが出来ない点にある。One method for bonding thermosetting composite structures is to interpose a thermosetting adhesive film between the surfaces to be bonded and simultaneously heat and pressurize the joint. This process requires relatively high heat (250°F to 35°F).
0°F) and high pressure (25 psi.min) for long periods of time (
This method cannot be used in practice because the treatment must be carried out at this temperature for at least 2 hours. Furthermore, when heating a wide range, thermal expansion due to the heat required in this process becomes a problem. This may also result in thermal strain and deformation when the structure is cooled due to differences in thermal expansion coefficients in the local structure. The disadvantage of thermosetting adhesives is that they can only be treated once and cannot be replaced if a part of the structure is damaged.

働力が必要となる欠点を有している。A second method currently in use involves bonding thermosetting composite structures by applying a thermosetting paste that hardens at room temperature to the joining surfaces in combination with mechanical fixing devices. It is. This method requires that the members to be joined be joined in advance, that a pilot hole be drilled, that this be disassembled, cleaned, and prepared for bonding. Adhesive is then applied to the mating surfaces and the parts are reassembled. The adhesive is then cured (usually about 24 hours at room temperature). In the next step, drill holes are drilled, expanded, and each fixing member is inserted through the hole and attached. This method has the drawback of using mechanical fixing members, which is costly and requires a large amount of labor.

である。A variation of these methods is to bond a film of thermoplastic adhesive interposed between and together with the thermoset composite structure. Thermoplastic materials can be repeatedly melted and rehardened, so that the bonding process can be reversed and the joined parts disassembled if desired. However, currently used thermosetting resins cannot be chemically bonded with sufficient strength using thermoplastic adhesives, and as a result, the bonding strength required for aircraft cannot be obtained. Therefore, this method is still unsuitable for joining members that require high joining strength.
